RE: Do you butcher your own deer
I've cut up -many a deer. Cleanliness is the key.
Use Bleach water, and often, to clean utensiles and cutting area.
I never age them on purpose. If you have a cut that you wish to age - take it out of the Freezer 3 or 4 days before you plan to cook it.
I don't mind butchering a deer at a time, but if I should take 2 - or someone donates a 3rd - I sometimes have it cut up and or smoked.
